g compound of equal parts of
powdered rosin, borax and flower of sulphur. Use a teaspoonful for a
ten-pound melting and make sure the compound is perfectly dry.

Stir a little and if metal is at proper heat there will be a flare,
flash or a little burning. A sort of tinfoil popcorn effect will be
noticed floating on top of the metal. Stir until this melts down. Have
your ladle hot and skim off soft particles. Dust the mould with mould
compound, a powder which makes the lead fill the entire grooves, and
not become cool before it does.

When everything is ready, fill the ladle and pour the lead into one of
the grooves. Hold the ladle above one end of the groove while pouring,
and do not move it along the groove. Fill the other grooves in a
similar manner.

Post Builders. These are moulds which are set over the stumps of posts
which have been drilled short in removing the inter-cell connectors.
Lead is then melted in with a burning flame to build the post up to
the proper height. Figure 100 shows a set of post-builders, and Figure
101 illustrates their use.

EQUIPMENT FOR GENERAL WORK ON CONNECTORS AND TERMINALS

Moulds for Casting Inter-Cell Connectors, Terminals, Terminal
Screws, Taper Lugs, Plate Straps, Etc.

Figure 102 shows a plate strap mould with which three straps and posts
may be cast in one minute. It has a sliding movable tooth rack for
casting an odd or even number of teeth on the strap.

[Fig. 102 Plate strap mould]

Figure 103 shows a Link Combination Mould which casts five inter-cell
connectors for use on standard 7, 9, 11, 13 and 15 plate batteries,
four end connectors (two Dodge tapers, and standard tapers, negative
and positive), one end connector with 3/8 inch cable used on 12 volt
Maxwell battery and on all other cars a wire cable, and one small wire
to connect with end post on batteries requiring direct connection. It
also casts two post support rings to fit standard size rubber covers
and to fit posts cast with plate strap mould, and two washers which
are often needed when installing needed when installing new or rental
batteries.
